or any other suitable material,

vided on corresponding extremities thereof with couplings 7 and 8,respectively. The coupling '7 may be of any suitable type adapted to bereadily connected with and disconnected from a faucet or other source ofwater or liquid under pressure, and the coupling 8 may also be of anysuitable type provided, if desired, with a screen 9, and adapted toadmit air or other gas in the conduit 6. The coupling, ends of theconduits and-6 extend separately out of a coupling 10 formed on oneextremity of a flexible hose 11 or the like provided therein withpassages 12 and 13 that form continuations of the conduits 5 and 6,respectively.

The opposite extremity of the hose 11 is provided with a coupling 14having two branches 15 and 16 which communicate with the passages 12 and13, respectively, and are enclosed'in a hollow handle 17 provided at oneend thereof with an opening through which the coupling 14 extends.

-The opposite end of the handle 17 is fitted in one end of a tubularguard or casing 18 and secured thereto, as by small machine screws 19 orthe 15, 16 are preferably formed of hard rubber or other suitable rigidsubstance vulcanized to or formed integrally with the hose 11.

The handle 17 may be of wood, metal, hard rubber, or any other suitablematerial, and said handle may be secured to or fitted on the guard orcasing 18 in the described or any other suitable manner.

Connected in any suitable manner with the branches 15 and 16 of coupling14 are conduits 20 and 21, respectively, which are made of metal andextend through the handle 1'7 into the guard or casing 18 that islikewise made of metal or other suitable material. This guard or casing18 is provided interiorly thereof with a manifold having a conduit orcompartment 22 connected in any suitable manner with the conduit 20, anda conduit or compartment 23 connected in any suitable manner with theconduit 21. This manifold is indicated broadly at 24 and said manifoldis preferably formed by an elongated box 25 of rectangular crosssection, and a cover 26 fitted on said box in spaced relation with thewall 27 thereof. The cover 26 has a fiuidtight fit with the box 27 andmay be secured thereto in any suitable manner. The box 25, in turn, issecured in any suitable manner to the guard or casing 18 within thelatter, and said guard or casing forms one wall of the box in opposedrelation with the wall 27 thereof.

The manifold 24 is provided with injector means preferably comprised bya plurality of injectors indicated broadly at 28. These injectors extendtransversely of the guard or casing 18 and are axially alined withopenings 29 in the wall thereof. The injectors 28 are each preferablycomprised by two tubes 30 and 31 of different diameters extending onewithin the other, the tubes 30 being secured to the wall 2'7 of box 25in any suitable manner and communicating with the compartment 23, andthe tubes 31 being secured to the cover 26 in any suitable manner andcommunicating with the compartment 22. The injectors 28 serve tomix gasand liquid received from the compartm nts 22 and 23, respectively, anddischarge jets or sprays of said mixture under pressure and at highvelocity through the openings 29 in the guard or casing for applicationto the body of a person as hereinafter described.

The guard or casing 18 is open at the end thereof opposite that carryingthe handle 17, and said handle is preferably hollow and provided thereinwith slots 32 extending between opposite annular end portions 33 and 34of the handle. The screen 9, and a screen 36 in the inner end of theconduit 21, prevent dirt or other matter from entering the variousconduits, the manifold, and the injectors, and thereby insure that saidconduits, manifold, and injectors will function properly and not becomeclogged or stopped up by any extraneous matter. The guard or casing 18may, if desired, be provided with lugs 37 which are secured to or formedintegrally with said guard or casing and fitted with rubber sleeves orthe like 38. Said lugs and sleeves serve to support the guard or casing18 when the apparatus or appliance is not in use, and the sleeves 38prevent marring or scratching of the surface of any equipment on whichthe apparatus or appliance might be supported.

The above described portable fluid massage apparatus or appliance may beused in tubs, pools, or other bathing places as, for example, in a tub39 such as indicated in Fig. 1 of the drawings. This tub 39 is equippedwith a mixing faucet 40 for hot and cold water received from anysuitable source through pipes such as indicated at 41. In this case, thecoupling 7 is connected with the faucet 40, and the Water under pressureis delivered through the conduit 5, passage 12, conduit in branch 16 ofcoupling 14, and conduit 21, into the compartment 23 of manifold 24. Theconduit 6, in the use of the portable apparatus or appliance as stated,is preferably supported by a hook 42 secured in any suitable manner tothe coupling 8 and detachably engaged over the upper edge of the tub 39to hold'said coupling in a position substantially as shown in Fig. 1 ofthe drawings. The water delivered under pressure into the compartment 23of manifold 25, as previously pointed out, passes through the tubes 30of the injectors 28, and tubes 31 thereof, and the openings 29 in theguard or casing 18. The tubes 30, as clearly shown in Fig. 3 of thedrawings, extend within the tubes 31 in spaced relation therewith, sothat the passage of water through the injectors in the manner stated,

creates suction in the compartment 22, the conduit 20, the passage 13,and the conduit 6, thereby drawing air into the compartment 22. This airis entrained by the water delivered through the tubes 30, mixedtherewith in the injectors 28,

and discharged therefrom through the openings 29 in the guard of casing18. The tub 39 may have previously been filled with Water beforeattachment of the portable apparatus or appliance to the faucet 40, orsaid tub may be filled by delivery of the water therein through saidapparatus or appliance after attachment thereof to said faucet. The tub39 is provided with the usual drain opening 44, stopper 47 therefor,drain pipe 48, and overflow outlet 45.

A person in the tub 39 may, through the medium of the handle 17, movethe portable fluid massage apparatus or appliance about the tub, andunder the surface of the water therein, as desired, and thus apply thejets or sprays disti'ons'of the :body with a beneficial and healthfuleflect thereon. The jetsor sprays consisting of a mixture of liquidand-gas dlscliarged under pressure and at relatively :high velocitybelow the surface of the Water and against the body of the persontherein produce, in eiiecha vibratory message on the body or the person,which massage may be-"of more or less vigorous character, inaccordancewith the pressure of the liquid as regulated by the :handle 40 or thefaucet l'i). Itwill,

of course, be understood that instead of delivering water or otherliquid under pressure to the portable apparatus or appliance, the air orother-gas could bedelivered thereto under pressureand the water could besupplied from the tub to *thefportable apparatus or appliance through In"either-case, the effect produced upon the body of *the'personis'substantiallythesamc, and the device would be connected with thesource or fluid under pressure, andoperated, in substantially the "samemanner. Various forms'of couplings could connected with the conduits 5and 6, for the form a fluid-tight joint. spout is then delivered throughthe tube 51 and the conduit 5 to the portable apparatus or apdeliverytherethrough of liquid and gas, respectively. In Figs. 5 and 6, forexample, there is shown a'form of expansible-coupling forconnection-with a iaucet'having a relatively large spout 49 and outletopening 50. ihis coupling consists of a tube-5i provided atone end withserrations 52 and thereby connected with the liquid ccnduitfi of theportable apparatus or "appliance. The opposite end of the tube 51 isprovided with a shoulder 53 engaging one side 'of a rubber ring '54which is fitt'edon the tube 51 against'said shoulder. A

ring '55 loosely mounted on the tube 51 is adapted to engage the rubber'ringfi l and expand the same when pressed therea'gainst by a nut 56.This nut "56 is fitted on a threaded portion 57 of the tube 51, and saidnut is provided with operating handies 58. When the coupling end of thetube 51 is inserted in the opening '50 of spout 49, the nut 56 is turnedby the handles 58 to press the ring against the ring 54 so that thelatter is expanded against the inner periphery of the spout 49 to Thewater from said pliance, as previously described. When it is desired todisconnect the apparatus or appliance from the spout 49, the nut 56 isturned by the loandies 58 to release the ring 55 from ring 54 so thatthe latter contracts and the coupling may be disconnected.

In the embodiment of the invention shown in Figs. "7 to 10, inclusive,the conduit 11, insteadof being connected with a portable apparatus orappliance, is connected with a normally stationary manifold.indicated'broadly at 59 and having substantially the same constructionas the manifold 24. In this case. the conduit 11 is provided at one endwith flexible branches so and 61 com municating with the Water and airpassages 12 and 13 (Fig. 2) respectively, which, in turn, cornmunicatewith the conduits 5 and 6, as before described. The branches 60 and 61are connected in any suitable manner with pipes 62 and 63, respectively,which connect with, and are secured in any suitable manner to, pipes orconduits G4 and 65 which are closcd'at their opposite ends by anysuitable means for this purpose; The pipes Stand 65 extend transverselyof the tub SQ-and have connected therewith, and extending at rightangles thereto, pipes or conduits 66 and 6'7,'respectively. The pipes 66and 67, in turn, are

connected through one end or the mam-tors 59,

with compartments or conduits Stenci -69 thereof, respectively. Theconduits '68 and 89 are separated =irb'm eaeh otner leagues-many of theman-ifold and at the o posite ends thereof, the con-" to-providefiui'dtig l'iit jc iints between the The lower part of the manuals 59provided a series of elongated box l ike compartments or conduits 70 ofrectangular "cross section and similar conduits or compartments "-71cats ding transversel or the on or at opposite-ends thereof andommunicating therewith as before described The upper part of themanifold b9 is constituted by a series or elongated channel shapeportions "72 and similar mo portions extending transversely of thetioiis 72 at opposite ends thereof and communi- Gating therewith. Themanifold 59 is provided with injectors each comprising a of tubes 74, 75of different diameters (intending one Within the other as in the ease ofthe ini'otors previously described. The tubesfm are to the conduits or-'conipartments to on the top- 'walls thereof and communicate with saidcompet tments as clearly shown in Fig. 9 or the drawings. The tubes '15are secured to the topof the channel members 7-2 and communicate withthe chainbers 69 formed by said members and the up er walls of theconduits or compartments 70. The manifold 59' is connected in anysuitable manner with cross members 76 made of channel iron or othersuitable material. These cross members '76, in turn, are secured anysuitable manner to a support 7'7 on the underside thereof. This support7'7 is provided with openings 7 8 axia'ly all-nod with the injectors'74; 75 and through which the latter discharge jets or sprays of fluidin a manner to be presently described. The support 7'7 has securedthereto in any suitable manner legs 79 which rest on the bottom of thetub 39 and are provided with pads "80 of rubber or other suitablematerial that prevent mar-ring or scratching of the surface of the tub.

When the tube 5 is connected with the faucet 40, as shown in Fig. '7 ofthe drawings, and the tube 6 is supported on the tub 39 by the hook 42,Water under pressure may be delivered from the faucet '40 through thedescribed connections therefor with the manifold 59, into thecompartments 68 thereof.

positioned on the sup-port '77. ,The tub 39 may I? have previously beenfilled with water from the faucet 40, or from the manifold 59, and thejets or sprays are delivered under water against the body of the personso as to produce a fluid vibra tory massage on the body of the personwith the The water asses upg wardlfy under pressure through the tubes'74 and resulting invigorating and healthful effect attending the same.

In the embodiment of the invention shown of the rotary type includinga'driven shaft 84 having fixed thereon a sprocket 85 around which passesa chain 86. The chain 86 also passes around a sprocket 87 which is fixedon the armature shaft 88 of an electric motor 89 supplied with currentfrom any suitable source. Mounted in the tub 39 in any suitable manner,is a support 90 arranged to be submerged in water supplied to the tub bysuitable faucets or the like (not shown). Mounted on the support 90 is astandpipe 91 connected through the medium of a pipe 92 with the inlet 93of the pump 82. The water is drawn from the tub through the standpipe91, the pipe 92 and the inlet 93 of the pump and forced back through theoutlet 95 of said pump through a pipe 96,-a fitting 97 connected withsaid pipe and the standpipe 91, a pipe 98 .connected with said fitting,and the manifold 83 which is connected with the last named pipe. Acontinuous circulation of water and air is thus maintained in thedescribed circuit including the manifold, the pump, and the connectionstherebetween.

The manifold is connected with and supported by the support 90 in anysuitable manner, and said manifold has a construction similar to that ofthe manifold shown in Figs. 7 to 10, inclusive, of the drawings. Themanifold 83, however, has

. connected with the upper conduit or compartment 99 an air pipe 94which extends upwardly toward the top of the tubSQ. The lowercompartment 100 of the manifold has connected therewith the pipe 98. Themanifold 83, as in the caseof the manifold previously described, isprovided with injectors for mixing and discharging liquid and gas, andthese injectors are each comprised by tubes 102 and 103 of differentdiameters extending one within the other, as clearly shown in Fig. 11 ofthe drawings. The tubes 102 are secured to the upper wall of thecompartment 100 and communicate with the interior thereof, and the tubes103 are secured to the upper wall of the compartment 99 and communicatewith the interior thereof The injectors 102, 103 are axially alined withopenings 10% formed in the support 90, so that when a person ispositioned on said support, jets or sprays of air and water will bedelivered from the injectors. through the openings 104 against the bodyof the person to produce a fluid vibratory massage action on the body ofthe person, with the resulting invigorating and healthful effectpreviously referred to. The air is supplied to the injectors 102, 103through pipe 98 and compartment 99, the water forced through saidinjectors creating suction in said pipe and compartment so that air fromthe atmosphere is drawn therethrough, entrained and mixed with the waterin the injectors, and discharged therefrom with the water, as beforedescribed. H

In the embodiment of the invention shown in Figs. 12 and 13 of thedrawings, a series of tubs 39, arranged in separate rooms orcompartments if desired, are connected with a single source of fluidunder pressure supplied to manifolds 105 in the several tubs from a tank106. For this purpose, the lower compartments or conduits 107 ofthemanifolds 105have connected therewith pipes 108, which, in turn, areconnected with a pipe 109 that is connected with the tank 106. Suitablevalves 110 may be provided in the pipes 108 to selectively orsimultaneously control the delivery of air or gas under pressure fromthe tank 106 into the compartments 107 of the manifolds 105. The tank106 has connected therewith one end of a pipe 111 provided with asuitable check valve 112 and having an opposite end connected with theoutlet 113 of a rotary air compressor 114. This compressor 114 may be ofany suitable construction including a driven shaft 115. Fixed on theshaft 115 is a sprocket llfiaround which passes a chain 117 that alsopasses around a sprocket 118 which is fixed on the armature shaft 119 ofan electric motor 120.

Motor 120 receives current from any suitable source and drives thecompressor 114 which therefore acts to supply the tank 106 withcompressed air or other gas, through the pipe 111.

The supply of air in the tank 106 may, if desired, be regulatedautomatically, and for this purpose there is mounted on said tank, incommunication with the interior thereof, a diaphragm 121 connected withone end of a lever 122 so as to rock the same about its pivot 123 as thepressure of the air in the tank 106 decreases and increases. The pivot123 for the lever 122 is provided by a bracket 124 secured in anysuitable manner to the tank 106, and the end of the lever opposite thatconnected with the diaphragm 121 has pivotally mounted thereon a lever125 arranged for limited swinging .movement on the lever 122 betweenpins 126 secured thereto. Carried by the lever 125 and insulatedtherefrom in any suitable manner is a contact 127 adapted to engagecontacts 128 carried by a bracket 129 and insulated therefrom in anysuitable manner.. The bracket 129, in turn, is secured in any suitablemanner on the tank 106. The contacts 128 are provided with suitableterminals 130 with which are connected lead wires 131 that, in turn,connect with one side of a source of electric current 132 and oneterminal 133 of the electric motor 120. The opposite side of the sourceof electrical current 132 is connected by a lead wire 134 with the otherterminal 135 of said electric motor.

When the tank 106 is sufficiently charged with air, the diaphragm 121moves outwardly thus tilting the lever 122 so that the contact 127 ismoved out of engagement with the contacts 128, and the motor 120 and thecompressor 114 are stopped. When the pressure of the air in the tank 106decreases sufficiently to enable the diaphragm 121 to move inwardly, thelever 122 is tilted so that the contacts 127 and 128 are engaged, thusstarting the motor 120 and the compressor 114, to recharge the tank 106.It will thus appear that the tank 106 is automatically charged each timethe pressure therein decreases sufficiently to enable the diaphragm 121to move and engage the contacts 127, 128, and that as soon as the tank106 is recharged, the motor and compressor will be stopped, as beforedescribed. The manifolds 105 are substantially the same in constructionand operation as those previously described, except that the aircompartments 107 are provided in the lower part of the manifolds andwater compartments 136 are provided in the upper part of the manifolds.The manifolds 105 are secured in any suitable manner to supports 137 anddepend therefrom as clearly shown in Figs. 12 and 13 of the drawings.The supports 137, in turn, are mounted in any suitable manner in theseveral tubs, and said supe tte, t ytddtithi smote o i "t te i tt w thet t i eve bs; n aid emn t tt nte W t r is uni d to he tu s? ens; d ainetherettqm b u t zle ettttt and de in lat e l t e it t 51pm); k
